Patented May 3, 1932 CRAWFORD C. LOOMIS, OF ILION, NEW YORK, ASSIG'N OR T REMINGTON ARMS GOM- PANY, INC., A QORPORATION OF DELAWARE JOINING DEVICE Application filed September 11, 1930. Serial No. 481,278.

This invention relates to joining devices and, for the purpose of illustration, has been shown as a joining device for securing the proper alignment of the wooden fore-end of a firearm with the metal receiver thereof. The invention contemplates an improved oining device for the attachment of such a fore-end.

In the drawings:

Fig. l is a. fragmentary side elevation of a firearm embodying the invention.

Fig. 2 is an enlarged fragmentary side elevation, partly in section.

Fig. 3 is a detail of the improved joining device.

The firearm comprises a barrel and a receiver 11 having secured thereto a magazine tube 12 which is partially or wholly housed in a fore-end piece 13. Said foreend piece is immediately in front of the receiver and, in assembling the gun, it is pressed into contact with the receiver by joining devices associated with the magazinc tube. The rearward part of the foreend comprises a tenon 14: adapted to be received in a suitable kerf in the forward end of the receiver. To better locate the foreend upon the receiver additional locating and securing devices, such as dowel pins, are usually provided. The use of dowel pins, however, presents a substantial difficulty for the reason that one end of the dowel pin is received in the wood of the fore-end while the other extremity of the dowel pin must enter the metal of the receiver. The pins are necessarily of small diameter to be received in the comparatively thin wood shell of the foreend it being remembered that the fore-end is substantially a wood channel which contains the magazine tube and the lower part of the barrel. Dowel pins of metal cannot be made to adhere to the wood. and on account of the thinness of the wood they readily split out. On the other hand, wooden pins which can be securely glued into the wood of the fore-end are readily broken off against the metal face of the receiver.

In order to overcome these ditliculties. the present invention contemplates the use of a dowel pin of the type shown in side elevation in Fig. 2 and in section in Fig. 3. The

body of the pin 15 is of wood, fibre or other suitable non-metallic material, the most of the part thereof which is received in the Wood of the fore-end being a plain cylinder, preferably of wood. Such a pin can be glued in place and become substantially a part of the fore-end, exhibiting no tendency whatever to split or crack the fore-end wood. The exposed end of the pin is somewhat reduced in diameter and rounded in the manner illustrated, and is covered with a metal cap 16. Preferably the base of this metal cap is slightly below the surface of the fore-end, as shown in Fig. 2, so that the projecting end of the pin has an unbroken metal surface and presents all the advantages of a metal pin for the purpose of aligning with and entering the pin receiving recess in the forward face of the receiver. The pin thus has the double advantage of comprising a surface of wood where wood is desirable and a surface of metal where metal is desirable.

While the drawings and the foregoing description have been prepared with reference to the use of the novel dowel pin in a firearm, it is to be understood that the invention contemplates all such uses thereof as fall within the broad interpretation of the appended claims.

lVhat is claimed is:

1. A device for joining members composed of materials of dissimilar character which comprises parts of dissimilar character which are similar respectively to the parts to be joined.

2. A device for joining a metal member to a wood member comprising a surface of metal adapted to engage the metal member and a surface of wood adapted to engage the wood member.

8. A dowel pin comprising a body of one material and a cap of another material partially enclosing said body.

l. A dowel pin comprising a body of wood and a cap of metal partially enclosing said body.

5. A fore-end for a firearm having secured therein and projecting therefrom a non-metallic dowel pin provided with a metallic cap.

6. A fore-end for a firearm having glued therein a Wood pin provided with a projectin metallic head.

Means for joining the fore-end and the receiver of a firearm comprising dowel pins of Wood, secured in said fore-end and pr0- vided with metal surfaced heads adapted to enter recesses in said receiver.
